FRANK A. EASTMAN, OF SAOO, MAINE, ASSIGNOR OF ONE-HALF TO WILLIAM IIARMON, OF SAME PLACE.

SAW-GUARD.

SPECIFICATION forming part of Letters Patent No. 617,239, dated January 3, 1899.

Application filed October 7, 1 8 9 8 T aZZ whom it may concern.-

Be it known that I, FRANK A. EASTMAN, a citizen of the United States, residing at Saco, in the county of York and State of Maine,

have invented new anduseful Improvements in Saw-Guards, of which the following is a specification.

This invention relates to improvements in saw-guards for circular saws, and it is carried out as follows, reference being had to the ac companying drawings, wherein- Figure 1 represents a side elevation of the improved saw-guard as applied to a circular saw. Fig. 2 represents a top plan View of the I 5 same. Fig. 3 represents a bottom plan view of the device. Fig. 4 represents a cross-section on the line 4C 4 shown in Fig. l, and Fig. 5 represents a cross-section on the line 5 5 shown in Fig. 1.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents the slitted work-supporting table, and B represents the circular saw, secured to the rotary shaft 1), as is common in devices of this kind. Below the table A is secured in an adjustable manner the angle-iron O, the horizontal portion of which is provided with alongitudinal slot 0, through which passes a screw-bolt D, secured to the table A and provided with a nut 01, by means of which said angle-iron may be adj ustably secured to the table A and adjusted forward and back relative to the saw in use simply by loosening the nut 01 and moving the angle-iron accordingly, after which it is secured in the adjusted position simply by tightening the said nut cl.

To the vertical portion of the longitudinally adjustable angle-iron O is secured a vertically-adjustable metal plate or spreader E, which is located in a line with the circular saw B, as shown. The lower portion of said Serial No. 692,879. (No model.)

F F F, after which said spreader may be moved up or down to the desired position for a purpose as will hereinafter be described, and after being so adjusted it may be secured in position simply by tightening the screws F F F.

To the upper portion of the spreader E is pivotally connected an arm or lever G, preferably by means of a screw-bolt H going through said arm or lever and one of a series of perforations E in the spreader E and having its end preferably screwed into a nut h, arranged in a recess in the opposite portion of said arm G, as shown in Fig. 5.

To the arm or lever Gis secured the cap or hood I, which covers and protects the upper portion of the circular saw B, as shown.

By adjusting the spreader E up and down relative to the table A the position of the cap or hood I is adjusted relative to the thickness of the lumber that is being sawed. The forward portion of the arm or lever G is made to rest on the forward upper portion of the spreader E, so as to hold said arm and hood or cap I, attached to it, in a horizontal position, as shown in Fig. 1.

By the construction and arrangement as hereinabove shown and described several advantages are obtained, among which may be mentioned that the cap or hood I serves as a proper cover above the saw and prevents articles that may fall upon the table from coming in contact with the saw, thus preventing accidents to the man in charge of the work; By the simple mechanism as described the spreader and cap pivoted to it may be ad justed vertically as well as horizontally rela= tive to the saw, as may be required, and the cap or hood may be adjusted forward and back relative to the spreader by pivoting it to any one of the perforations E on the said spreader, as may be desired.

In case it is desired to rabbet a plank the spreader and the case or hood attached to it may easily be removed simply by loosening 5 the bolts F, after which the spreader and its attachment may readily be removed without the removal of said bolts from the angle-iron G or the removal of the latter from the table A.

nuts engaging said bolts and bearing on said upright or spreader whereby to detachably and adj ustably secure it to said angle-iron, and a cap or hood pivotally secured to said upright and supported on the upper edge thereof, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
